Can a Nikon digital camera double as a webcam?

I have been wanting to get a digital camera for awhile now. I had a webcam, but something happened to it and I do not want to have to replace it AND get a digital camera, when I know that some cameras can also be used as webcams. I know that Nikon is a good company but I do not know if their cameras are webcams. If they do not make those types of cameras, can anyone tell me what makers DO have a good quality camera + webcam for a decent price?

Yes, I think it can.

Not possible
